Over the past month I’ve pretty much been confined to the couch because of foot surgery, which means I’ve had a bit more time to do some channel surfing and finally learned how to watch programs “On Demand” (I know, I’m way behind the times). What I found was the Documentary Channel and what I watched were two pretty interesting documentary films called “Tapped” (produced in 2009) and “Bag-It” (produced in 2010).

Back in the early 1960s, I was living in the Ocala National Forest in an area between the Oklawaha River and the St. Johns. My great-grandfather, Anderson Roberts homesteaded here when Florida was still just a territory.

K. M. of Old Town writes, “I’ve got a question…last month you wrote about taking a gun into a bar being illegal, but taking a gun into a restaurant wasn’t, if you have a concealed weapon permit. What about a knife? What’s the rule there?

A look at history shows us that our energy sources have never remained static, with renewables such as wind and solar widespread several times in the past millennia, only to be displaced by a glut of cheap fuel.

Some sources become obsolete as their time has passed; others are taken over by their competitors as we are seeing with oil and coal.

The U.S. stopped the direct use of coal and oil for transportation and buildings in the 1920s and 1960s, respectively.
